22 mm AFL Valve Comp DZR Nickel c/w Lever

Quarter turn Servicing Valve with a ball capable of accepting an Automatic Flow Limiting Cartridge to limit the flow of hot and cold water according to its flow rate. A side port allows the Cartridge to be fitted inside the ball after the valve has been installed. Cartridges can be removed in service through the side port without draining the system. Knowing the maximum flow rate enables the designer to accurately size pipes, pumps, heaters and the supply system. Limiting the flow can save water and/or assist with balancing thereby preventing some appliances, at higher level or farther downstream, are starved of water. A colour-coded Identity Disc stating the flow rate and "Arrow Valves 01442 823123" is fitted to the knurled Plug to indicate the Cartridge inside. Valves should be installed, the system flushed and chlorinated before the Cartridges are inserted.
